In this article, we’ll discuss where you can find the card number on your green card and why it is essential. 

Structure and Format of the U.S Green Card Number

The U.S Green Card number is a 13-character number, also known as the USCIS number. Knowing the format of the number will give you an idea of what it means and what information it holds. Here’s what it entails:

1. Prefix

The U.S. Green Card Number starts with three letters, which are the prefix. USCIS uses these letters internally to categorize and track different types of cases. The prefix helps differentiate between various types of applications and petitions that USCIS processes.

2. Numeric Sequence

After the three letters is a 10-digit sequence. This sequence is unique to each Green Card holder and is assigned sequentially as applications are processed. The sequence ensures that each U.S. Green Card Number is unique so individual cases can be tracked precisely.

3. Year of Issue

Within the numeric sequence is the year the Green Card was issued. This helps USCIS to reference the year of issue which can be essential to verify the card and the timeline of the individual’s residency.

4. Case Number

The numeric sequence also has the individual’s case number, which links the Green Card to the immigration application. This connection between the Green Card number and the case number allows USCIS to pull up and review the applicant’s file and to maintain continuity in record keeping and case management.

5. Check Digit

Some Green Card numbers have a 13th digit, which is the check digit. This digit is used to verify the entire number to prevent data entry errors and to ensure the information is accurate.

Locating Your U.S. Green Card Number

Individuals commonly ask, “Where can I find card number on green card?”. Finding your Green Card number on your Permanent Resident Card is easy once you know where to look. The Green Card number, also known as the USCIS number, is on the front side of the card. Depending on the version of the card you have, it may be in a slightly different spot: 

1. U.S Green Cards Issued after May 2010 

On the newer versions of the Green Card, the number is on the front side of the card, bottom section. It’s labeled as “USCIS#,” followed by the 13-digit number. This format is three letters followed by ten digits. 

2. Older Green Cards (issued before May 2010)

On older versions, the U.S. Green Card Number is on the front of the card but in a different spot. It’s usually in the middle or lower part of the card and labeled as “A#” followed by numbers. 

3. Card Design

The U.S. Green Card Number is embedded in the card design to prevent counterfeiting and tampering. The design features holographic images, fine-line patterns, and color shifts. 
Make sure you know where to find your Green Card number for immigration forms, to renew your card, or to show proof of your permanent resident status to employers, government agencies, or institutions. Also, ensure it’s readable and matches your official records to avoid problems.

Use of the Green Card Number

The number is a key identifier for lawful permanent residents in the US and is used in many situations. Knowing when and why you need this number will help you better navigate legal, employment, and administrative processes. 

1. Employment Verification

 Employers in the US are required to verify the employment eligibility of all employees. During the hiring process, new employees must fill out Form I-9, Employment Eligibility Verification.

2. Travel and Re-entry

When a Green Card holder travels outside the US, they must present their Green Card upon re-entry to prove their permanent resident status. The Green Card number helps US Customs and Border Protection (CBP) officers quickly verify the individual’s status so you can re-enter the country smoothly. 

3. Applying for Benefits

Permanent residents may be eligible for some public benefits and services such as Social Security, Medicare, and financial aid for education. When applying for these benefits, you may be required to provide your Green Card number as part of the verification process to prove your eligibility. 

4. Renewal and Replacement

Green Cards are valid for ten years and must be renewed before expiration. If you lose, damage, or have your card stolen, you must replace it. You need the Green Card number for these processes to maintain continuous immigration records and issue a new card.  

5. Legal and Administrative Processes

In legal matters such as court proceedings or when dealing with government agencies, providing the Green Card number helps to identify and reference the individual’s immigration status. This can be important for immigration status verification, deportation defense or other legal issues. 

6. Loan and Mortgage Applications

Financial institutions may require proof of lawful permanent residency when applying for loans or mortgages. The Green Card number along with other personal information is used to verify the applicant’s identity and eligibility for financial products. 

7. Educational Enrollments

When enrolling in educational institutions, especially for higher education, students may need to provide their Green Card number to verify their residency status. This can affect in-state tuition rates, scholarships, and other educational benefits. 

8. Healthcare Services

Some healthcare providers and insurance companies may require a Green Card number to verify eligibility for specific services and programs. So permanent residents can get the right coverage and benefits. 
The Green Card number is a valuable and essential tool for lawful permanent residents, for many aspects of daily life, and for complying with US laws and regulations. Need help in obtaining a green card? allows you to connect with verified attorneys and access legal information. Sign up for

Renewal and Replacement Processes

The Green Card number is vital to the renewal and replacement process of a Green Card to ensure continuity and accuracy in an individual’s immigration records. Here’s how it works in these situations: 

Renewal Process

Green Cards are good for ten (10) years, and holders must apply for renewal before their card expires to maintain their permanent resident status. The renewal process is Form I-90, Application to Replace Permanent Resident Card. During this process, you must provide your Green Card number. USCIS accesses your immigration history, verifies your renewal eligibility, and links the new Green Card correctly to your existing records using this number.

Replacement Process

If you lose your Green Card, or it gets stolen, damaged, or contains incorrect information, you must replace it. Like the renewal process, the replacement process requires Form I-90. You need the Green Card number so USCIS can access your file, verify your identity, and process the new card. The Green Card number stays the same to keep your immigration records consistent.

Expedited Processing

In some situations, such as employment authorization or international travel, you may need an expedited Green Card replacement. Providing the Green Card number allows USCIS to quickly find and review your file, speeding up the issuance of your new card.

Updating Information

When you renew or replace a Green Card, you may need to update personal information like your address or name. The Green Card number updates this information in your immigration records, preventing confusion or legal issues.

Communication with USCIS

During the renewal or replacement process, USCIS may contact you for more information or verification. The U.S. Green Card Number is used in all correspondence, so there’s no confusion between you and USCIS. 
The Green Card number is the key to the renewal and replacement process; it’s how USCIS identifies and verifies you. It ensures all updates and new issuances are linked to your immigration records so your permanent resident status remains intact.
